Exam Details

The Delaware Master HVACR examination is part of the professional licensing process administered through the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners. Applicants pursuing licensure by examination must receive approval before scheduling the test with the approved examination provider.

The examination evaluates knowledge associated with heating, refrigeration, air conditioning, ventilation, process cooling, process heating, gas piping, equipment, system sizing, installation, testing, and inspection. Candidates should be ready to apply technical principles and locate information across several references.

General HVACR knowledge may include refrigeration principles, temperature-pressure relationships, heat transfer, airflow, humidity, combustion, electrical fundamentals, tools, safety practices, system operation, and common trade terminology.

Fuel-gas preparation may include gas-piping materials, sizing methods, regulators, shutoff valves, appliance connections, combustion air, venting, pressure testing, clearances, and installation safety. Candidates should practice using the tables and conditions found in the International Fuel Gas Code.

Mechanical-code preparation may include equipment installation, ventilation, exhaust, duct construction, combustion air, refrigeration systems, boilers, chimneys, vents, clearances, supports, and system protection.

Equipment questions may involve furnaces, boilers, heat pumps, compressors, condensers, evaporators, metering devices, air handlers, burners, controls, safety devices, refrigeration equipment, and air-conditioning systems.

System-sizing subjects may include residential heating and cooling loads, equipment selection, airflow, friction rate, velocity, duct dimensions, and distribution-system design. Manual J and the Ductulator support preparation for these calculation and sizing subjects.

Testing and inspection preparation may involve pressure tests, leak checks, equipment startup, operational verification, safety controls, performance measurements, inspection procedures, and evaluation of completed installations.

Candidates should divide study time among theory, code requirements, equipment knowledge, calculations, and reference navigation. A balanced preparation plan is more effective than concentrating only on one publication or one type of question.

Open Book Test

The Delaware Master HVACR examination is an open-book test. Candidates may use authorized printed references under the examination provider’s current rules.

An open-book format does not remove the need for preparation. The included references contain extensive technical information, and candidates may not have enough time to research every question from the beginning. Efficient performance requires subject knowledge and familiarity with each book.

The highlighted and tabbed rental materials are prepared to support faster navigation. Tabs create recognizable locations for major chapters, code subjects, formulas, equipment topics, and calculation methods. Highlighting helps selected information stand out during repeated review.

The International Fuel Gas Code should be used for subjects involving fuel-gas piping, appliance connections, pressure regulation, combustion air, venting, testing, sizing, materials, and installation requirements.

The International Mechanical Code supports questions involving mechanical equipment, ventilation, exhaust systems, duct construction, refrigeration, boilers, combustion air, chimneys, vents, and installation clearances.

Low Pressure Boilers supports review of boiler construction, operation, controls, fittings, burners, safety devices, water systems, maintenance, inspection, and operating procedures.

Modern Refrigeration and Air Conditioning provides broad technical coverage of refrigeration cycles, refrigerants, compressors, condensers, evaporators, metering devices, air-conditioning systems, heat pumps, electrical controls, heating systems, troubleshooting, and service procedures.

Residential Load Calculation – Manual J supports residential heating and cooling load calculations. Candidates should understand how insulation, windows, doors, orientation, infiltration, occupancy, climate, and internal gains affect system loads.

The Ductulator supports duct-sizing work involving airflow, friction rate, velocity, and duct dimensions. Candidates should practice using it repeatedly before exam day so that adjustments and readings can be completed efficiently.

Highlighted information must still be read in context. Definitions, exceptions, table notes, equipment conditions, and surrounding provisions may affect the correct answer. Tabs and highlighting support navigation but do not replace understanding the complete material.

Candidates should review the current testing rules before bringing reference materials into the exam. Requirements may address permanent tabs, highlighting, handwritten notes, loose paper, added inserts, removable markers, photocopies, calculators, and other test-day materials.

Licensing Steps

Begin by reviewing the Delaware Master HVACR license scope and confirming that it matches the services you plan to provide. Delaware also offers restricted HVACR classifications for designated specialties.

Create an account through Delaware Professional Regulation Online Services and begin the Master HVACR application in DELPROS. Applications and required attachments are submitted through the state’s online licensing system.

Gather the documents required for the selected licensing pathway. These may include license verifications, employment records, apprenticeship documentation, certification records, and other supporting information requested by the Board.

Applicants for an unrestricted Master HVACR license must submit a copy of their CFC Certification card. Applicants should also arrange for the required work-experience verification to be submitted in the form accepted by the Board.

An applicant with an acceptable journeyman certificate must submit a copy of the apprenticeship program Certificate of Completion and proof of at least two years of qualifying work experience under the supervision of a master licensee after receiving the certificate.

An applicant without an acceptable journeyman certificate must submit proof of at least seven years of qualifying work experience under the supervision of a master licensee. The Board reviews the experience and determines whether an Apprenticeship By-Pass Examination is required.

Submit the completed application and supporting documentation through DELPROS. The Board must review and approve the application before the candidate can sit for the Master HVACR examination.

After approval, follow the examination provider’s registration and scheduling instructions. Review all identification, testing, calculator, reference-material, and appointment requirements before the examination date.

Use the six-month online course and highlighted and tabbed rental references to prepare. Complete technical review, code-navigation exercises, calculation practice, duct-sizing work, and timed study sessions.

Complete the examination and earn the required passing score. After the Board receives the official passing result and confirms that all licensing requirements have been completed, the license can be issued.

State Requirements

A Delaware Master HVACR license permits the license holder to design, install, construct, maintain, service, repair, alter, or modify products and equipment, including gas piping, used in heating, air conditioning, refrigeration, ventilation, process cooling, and process heating systems.

A Master HVACR Restricted license is limited to the specialty named on the license. The available restricted areas include forced-air heating, ventilation and gas piping; hydronic heating and gas piping; commercial hood systems; refrigeration; air conditioning; and gas piping.

Professionals who plan to provide services in more than one restricted specialty should pursue the unrestricted Master HVACR license. Existing restricted licensees must use the applicable process when seeking to upgrade to an unrestricted license.

A Master Plumber license is also required when the work involves systems used to bring water into a building or remove liquid and water-carried waste. The Master HVACR license does not replace plumbing authority for that work.

Applicants must provide license verification from jurisdictions in which they currently hold or previously held a professional license when required by the application. Work-experience documentation is also required for the applicable examination or reciprocity pathway.

Acceptance of employment and experience records remains subject to Board review. Applicants should provide complete, accurate, and consistent documentation to reduce application delays.

Candidates must obtain a passing score of at least 70 percent. Applicants who do not pass after three attempts must reapply and obtain Board approval before testing again, and the state’s waiting requirements apply.

Plumbing and HVACR licenses expire on October 31 of even-numbered years. Licensees must complete the renewal process through DELPROS and satisfy the continuing education requirements associated with their licensing period.

A Delaware professional HVACR license is separate from a business license. Individuals planning to operate an HVACR contracting company may also need a legal business entity, business registration, tax accounts, insurance, and other operational approvals.
